' safety, hair cutting device and has for its objects: y

1. To provide an improved adjustable hair cutting device for home orcommercial use.

2. To provide an improved means of adjusting a hair cutting device thatit ma effect a close cut or otherwise at the wil of the operator.

3. To provide an im roged means of securely holding the cuttlng unit orblade in a hair cutting device.

. 4. To provide an improved means of securing the cutting unit of a haircutting de vice to its body portion.

5. To rovide an improved means for withdrawing or extending the guardportion of a hair cuttin device.

6. To provide an improved run in which the ard portion of my device isintended to slide. I

7. To provide an improved blade holding device that adequately'protectsthe blade, and through integral means secures the same in position.

I 8. To provide an improved method ofhinging the blade holding portionsto a' hair cutting device.

9. To provide a blade holding device having thereon means of protectingthe inner edge of the cutting blade from contacting with the holdingframe of a hair cutting device.

10. To provide an ,improved means of holding the cutting blades in theiroperating position.

11. To jack for the operating of the guard portion of my device. And tosecure other advantages, many of which will be hereinafter referred toin the description of the various parts.

vice showing its general appearance assem-j bled ready for use. i

Fig.- 2 is a view showing a section through line 2-2 of Fig. 1 with oneblade holding unit in position to receive a blade.

Fig. 3 is a longitudinal section showing my improved adjustable guard.

Fig. 4 1s a view of the inner side of my improved blade carrying unit.

Fig. 5 is a view showing the inner side of Q my improved blade carryingunit to accommodate a single edge blade.

Fig. 6 is a view of the double edged outtin blade used in my device.

ig. 7 is a view of a single'edged cutting blade for use in the modifiedsingle blade holding unit shown in Figure 5.

Fig. 8 is a view of my improved blade holding unit locking pin.

Referring again to Fig. 1, A designates Q the handle of my improveddevice. B is the guard. C designates the blade holdin unit. D1 shows amovable hin ing pin wit its inner end tapered at D an its outer endknobbed at D E is a hinging lug or projection on the handle A, throughwhich lug the pin D passes in forming a hinge with the lugged portion ofthe blade carrying unit G. F designates the blade holding unit tension sring, hinged at G on the handle unit A. is a thumb nut turning on thethreaded portion Lthe operation of which furnishes regulating means ofprojecting or withdrawing the teeth on the guard unit B which moves tothe desired positions of ad-' justment in the pocket Q. (See Fig. 3.)

Referring again to Fig. 2, J designates a two ed e cutting blade as usedon In -device. is a projecting lip upon the lade carrying unit C shapedto engage the edge of. the orifice, in the blade J, next to the usedcutting edge, (see also Fig. 6) so as to prevent contact of the unusedcutting edge with the body portion of m device.

Referring again to guiding pin on the handle unit A, operatin in theslot M in the guard B, so as tofurnis at all times a'steadying force onthe uard hooked projection beneath which the blade ig. 3, L designates aJ fits and is held. P designates a projec-..

tion on the hinged leaf S, which extends throu h an aperture in theblade carry ng unit Said projection P is shaped to engage the edge ofthe orifice, in the blade J, next to the unused cutting ed e, and inconjunction with the projection operates to firmly hold the blade J inits cutting position on the unit C.

Referring again to Fig. 5, N' shows a lipped projection on my modifiedsingle edge blade holding unit. K designates a shoulder on the modifiedsingle edge blade holding unit C against which shoulder the back of thesingle edge blade rests and is held. P shows a projection on, the hingedportion S which projection extends through the aperture in-the unit 0',and engages the edge of the reinforcement on the back of the blade andlocks the single edge blade in its cutting position on the single edgeblade holding unit C. Similar letters refer to similar parts throughoutthe several drawln s.

Iy novel and improved safety hair cutting device comprises the carryinghandle A, which may be of any design consistent with its purpose, towhich are hinged a series of blade holding units, tensioned in theiroperating position b means of the holding sprin F. (Fig. 1 Intermediatethe blade hol ing-units the guard B, in the ocket Q, is re lated to anydesired proection by turning the thumb nut H upon the threaded portionI, which turning in the slot R causes the guard to extend or recede atthe will of the operator. (Fig. 3). The operation of the pin L in theslot M insures the guard moving uniformly straight, and avoids binding.

The portions C swing on their'hinges by withdrawing the pins D so as toeliminate the tensioning force upon the spring F, thus making possiblethe easy removal of the cutting blades.

t will be understood that while the appended claims are drawn in thesingular they as well cover any number of the units described when usedin series.

Having thus described my invention, I claim as new and desire to secureby Letters Patent of the United States.
